Topologie sur l'ensemble des parties positives d'un réseau

Cédric Bonnafé

We define a notion of {\it positive part} of a lattice and we endow the set of such positive parts with a topology. We then study some properties of this topology, by comparing…

Note on the Deodhar decomposition of a double Schubert cell

Olivier Dudas

We show that for an algebraic reductive group , the partition of a double Schubert cell in the flag variety defined by Deodhar, and coming from a Bialynicki-Birula decompo…

A reduction method for noncommutative -spaces and applications

Uffe Haagerup, Marius Junge, Quanhua Xu

We consider the reduction of problems on general noncommutative -spaces to the corresponding ones on those associated with finite von Neumann algebras. The main tool is a unpu…

Semi-continuité des cellules de Kazhdan-Lusztig

Cédric Bonnafé

Computations in small Coxeter groups and infinite dihedral groups suggest that Kazhdan-Lusztig cells for unequal parameters obey to some "semicontinuity" phenomenon (as the paramet…
